It was a star-studded afternoon at Coldwater Park in LA on Saturday. Jessica Alba  wore a TEXTILE Elizabeth and James  cardigan to bring her daughter Honor to play on the swings and hang in the grass as Rebecca Gayheart and Eric Dane  entertained their little one, Billie. The Hollywood parents chatted with each other while tending to their girls. Eric was able to enjoy the sunny weather with his family now that Grey's Anatomy wrapped with an exciting season finale  last week. Eric and Rebecca's Summer plans  include moving into a new home, and he hopes to teach little Billie how to swim. Jessica, meanwhile, made the casual outing before heading to a friend's wedding  that evening with Cash Warren, and the festivities were intense enough that Jessica tweeted that a p.m. nap was in order yesterday.
